A microwave reaction vial was charged with 5-bromo-3-iodo-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridine (408.03 mg, 1.0 mmol), 1H-pyrazol-3-ylboronic acid (117.49 mg, 1.05 mmol), 1,1′-Bis(diphenylphosphino)ferrocenepalladium (II) chloride (81.66 mg, 0.1 mmol), 1.00 M of Potassium acetate in Water (1.5 mL, 1.5 mmol), 1.00 M of Sodium carbonate in Water (1.5 mL, 1.5 mmol), and Acetonitrile (3 mL). The reaction mixture was heated under microwave at 100° C. for 20 minutes. Added another 2 equivalents of 1H-pyrazol-3-ylboronic acid and continue heated under microwave at 100° C. for 20 minutes. The same procedure was repeated 2 more times. The mixture was concentrated and the residue was purified on silica eluted with 0 to 100% Ethyl acetate in Heptane to afford 5-bromo-3-(1H-pyrazol-3-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridine as an off-white solid (153.7 mg, 44%).
